摘要： Manufacture of an aluminum-aluminum oxide dispersion composite conductive material (hereinafter referred to as Al-Al.sub.2 O.sub.3 dispersion composite conductive material) by compacting aluminum powder prepared by the atomization method, the particles having an oxide film with a thickness of about 100 A, and heat-treating the resultant compacted material in a vacuum or in a reducing gas or inert gas atmosphere at a temperature of 660.degree. to 700.degree.C. The composite conductive material thus obtained has a structure, in which the aluminum oxide is uniformly dispersed in aluminum, and it is capable of high speed wire drawing. Its electrical conductivity is 56.5 to 63.2 percent IACS (International Annealed Copper Standard), and its aluminum oxide content is 0.01 to 0.2 weight percent.

摘要： A method and apparatus for cutting simultaneously a plurality of glass fibers at an uncoated end portion so as to provide smooth mirror planar cut surfaces. The method of the present invention comprises the steps of removably securing each of the fibers on either side of a cutting point, placing each of the secured fibers on a resilient material provided in the region of the cutting point, scoring the outer surface of each of the fibers at the cutting point, and arcuately bending each of the fibers between the secured portions so as to impart a tension along the axial direction of each of the fibers, whereby the cutting occurs at the cutting point. Two embodiments of the apparatus of the present invention which perform the cutting operation in accordance with the method of the present invention are disclosed.
